Homework Help: Chemistry

Posted by Saifeena on Wednesday, April 18, 2012 at 4:01pm.

from a calorimeter experiment I got this calculation:

Cm=30g(4.184 J/g(Celsius))(24 Celsius-20.8Celsius)/-25g(24 Celsius-99.6 Celsius)

gives
Cm= .107 J/g(Celsius)

I have the answer here above, but when I calculate it I get different answers could someone please explain how I can get .107 J/g(Celsius) I don't understand how. Thank you!
